Mentions:
The mean values of the HRV time-domain indices were reduced in the post-exercise period compared to the resting period in both groups (time effect: p < 0.01 for all analyses), however there was no difference in this response between NT and HT (group vs. time interactions: p = 0.2–0.4 depending on the index analyzed; Figure 2). Regarding the frequency domain indices, we observed a significant reduction in the LF (ms2) and HF (ms2 and nu) and an increase in the LF (nu) and LF/HF in the post-exercise period in comparison to resting values (time effect: p < 0.01 for all analyses), with no differences between groups in these responses (group vs. time interactions: p = 0.2–0.8 depending on the index analyzed; Figure 3).
